A display device comprises an anode, a cathode, and a luminescent region disposed between the anode and the cathode, wherein the anode comprises a metal-organic mixed layer operatively combined with an electron-accepting material. An anode may comprise a mixture of a metal-organic mixed layer and an electron-accepting material within a single layer of the anode. Alternatively, the anode may have a multilayer configuration comprising a metal-organic mixed layer and a buffer layer adjacent the metal-organic mixed layer, wherein the buffer layer comprises an electron-accepting material and optionally a hole transport material.
